@lucianobuszmicz This seems to be a common issue with the Pixel 7. I've linked a [link|https://www.reddit.com/r/GooglePixel/comments/y5n3kn/pixel_7_pro_microphone_issue/|thread|new_window=true] here that you may find helpful. Someone suggests cleaning out the microphone hole with first a vacuum then blowing air into it. It is possible that during the screen replacement process, some finger dirt or perhaps adhesive from the screen got into the microphone.
